We report a case of lymphoepithelioma-like carcinoma of the skin on the right cheek of a 67-year-old man. Histologically, the entire dermis was occupied by multiple lobules of atypical epithelial tumor cell nests surrounded by inflammatory cells. Immunohistochemical examination showed that the epithelial tumor cells were positive for cytokeratin and epithelial membrane antigen. The inflammatory...

Calcifying epithelial odontogenic tumor (CEOT) is a benign epithelial odontogenic tumor occurring most frequently in the posterior part of the lower jaw. Extraosseous CEOT is one of the rarest forms of this tumor, and few such cases involving the maxillary gingiva have been reported in the literature. Here we present a case that showed progressive enlargement in the left maxillary gingival area...

Nasopharyngeal carcinoma (NPC) is a malignant that appears in the epithelial lining of nasopharyngeal mucosa. Genetic predisposition, environmental risk factors, nutritional and Epstein-Barr virus (EBV) infection are main factors for NPC. virus, human cancer-associated present more than 90% people worldwide. Latent Membrane Protein 1 (LMP1) has been identified as converting oncoprotein. LMP1 wa...

Background and Aim: Oral mucosal lesions have various prevalence rates among different populations. Few studies have evaluated the frequency of oral mucosal lesions in Iranian population. This study aimed to determine the frequency of oral mucosal lesions and the related factors.                   &nb...

Tumor evolution and stable resistance state identification remains the main challenge for successful targeted tumor therapies. Previously our group has identified distinct cell trajectories in patient advanced basal carcinomas (BCCs) have molecular basis, surface markers for, reversibility of, transcription factor driver of to squamous carcinoma transition (BST). In addition differentiated stat...
